Plug Lock Options

Our patented Lunette Ring Lock, The Plug, is made of a cast iron alloy, and includes three components: the ring insert, lock collar, and lock mechanism. The ring insert goes inside the lunette ring (from the bottom) and mates with the lock collar (from the top). The Plug’s raised collar protects the lock from tampering. The Plug is sold to fit two hitch sizes (for 2 & 3/8″ and 3″ lunette rings) and is available with 3 lock options.

I have 2 of these locks and they are awesome! I am ordering another for my gooseneck trailer. These locks are VERY heavy duty.
